The invention relates to an oscillatory drive having an output shaft that can be driven to perform a rotationally oscillating movement about its longitudinal axis and that comprises a free end, a holding fixture at the free end of the output shaft comprising a contact surface for attachment of a tool, a mounting section on the holding fixture, raised relative to the contact surface, that projects to the outside in the direction of the longitudinal axis and that is designed for form-locking connection with a mounting opening of a tool placed in contact with the contact surface, and having a securement for fixing the tool with its mounting opening on the holding fixture, the securement permitting the tool to yield in axial direction under the action of a torque, against a pre-stress, and the mounting section permitting the tool to rotate by a certain angle of rotation when the tool gives way axially.

Oscillatory drive

A hand-held power tool () is specified, comprising a work spindle () for driving a tool (), said tool () being fastenable between a fastening element () and a holding portion () on a tool end of the work spindle (), and a displacement device () for sliding the fastening element () between a released position in which the fastening element () can be detached from the work spindle () and a clamped position in which the fastening element () is clamped against the holding portion () by a spring element (). The fastening element () includes a clamping shaft () that is insertable into the work spindle () and held in the clamped position by a lock assembly () inside the work spindle (), and which can be removed when in the released position (FIG.).
